Description

Technical Field

[0001] This application relates to the field of composite material technology, and in particular to a novel composite structure plate. Background Technology

[0002] In fields such as construction and furniture manufacturing, wood-based panels are a widely used basic material. Currently, the most common types of wood-based panels on the market are plywood and particleboard.

[0003] Multi-layer plywood is typically made by rotary cutting or slicing logs into veneers, applying glue, and then gluing adjacent layers perpendicular to the grain direction. It boasts advantages such as high strength, structural stability, good impact and vibration resistance, and good elasticity and toughness. However, multi-layer plywood also has some drawbacks. Firstly, its production requires high-quality raw materials; for example, high-quality poplar veneer requires robust poplar trees that have grown for many years. With increasingly scarce timber resources and a severe shortage of large-diameter timber, raw material costs are constantly rising. Secondly, when multi-layer plywood is used for veneer panels, a veneer material is often pressed onto the surface to meet aesthetic and functional requirements. This not only increases production costs but also places higher demands on the performance of the outermost layer material. Furthermore, during multiple hot-pressing processes, quality problems can easily arise, such as voids, delamination, deformation, surface carbonization, exposure of underlying defects, and burrs, affecting the flatness of the board.

[0004] Particleboard is a type of engineered wood product made by gluing together wood chips or other lignocellulosic materials with adhesives under heat and pressure. The advantages of particleboard include a smooth surface, uniform material, relatively low cost, and the ability to be finished with various veneers to achieve different aesthetic effects. However, particleboard also has its disadvantages. For example, its strength and nail-holding power are relatively weaker than plywood, which may not meet the requirements of some applications with high strength requirements. Furthermore, its water resistance is relatively poor, making it prone to swelling and deformation in humid environments.

[0005] Furthermore, due to limitations in manufacturing processes and structures, traditional plywood and particleboard cannot simultaneously combine the advantages of both without significantly increasing costs. Therefore, developing a new type of board material that integrates the characteristics of both plywood and particleboard while reducing costs and improving overall performance has become a pressing issue for those skilled in the art. Summary of the Invention

[0006] In view of this, this application provides a novel composite structure board that achieves a good balance between cost control and performance improvement, providing a more cost-effective and adaptable new material option for industries such as building materials and furniture manufacturing. It has broad market application prospects and can effectively overcome the defects of the existing technologies.

[0007] This application provides a novel composite structure board, which includes at least one layer of wood veneer and at least one layer of particleboard, wherein the wood veneer and particleboard are randomly arranged in combination and the wood veneer and particleboard are bonded and fixed together.

[0008] Preferably, the novel composite structure of the board includes wood veneer, particleboard, wood veneer, particleboard, wood veneer, particleboard, wood veneer, particleboard, and wood veneer connected in sequence, and the boards are bonded and fixed together.

[0009] Preferably, the novel composite structure board comprises particleboard, wood veneer, particleboard, wood veneer, particleboard, wood veneer, particleboard, wood veneer, and particleboard connected in sequence, and the boards are bonded and fixed together.

[0010] Preferably, the novel composite structure of the board includes particleboard, wood veneer, wood veneer, wood veneer, wood veneer, wood veneer, wood veneer, and particleboard connected in sequence, and the boards are bonded and fixed together.

[0011] Preferably, the novel composite structure board further includes at least one reinforcing layer, which is disposed between the wood veneer and the particleboard.

[0012] Preferably, the reinforcing layer is selected from at least one of fiber mesh, bamboo curtain, thin steel plate, aluminum foil, metal mesh, and cement fiberboard.

[0013] Preferably, the fiber web is made of at least one of glass fiber web, polyester fiber web, and aramid fiber web, and the mesh count of the fiber web is 40 to 100 mesh.

[0014] Preferably, the wood veneer is made of at least one of eucalyptus, pine, mixed wood, poplar, fir, birch, alder, and rubberwood.

[0015] Preferably, the particleboard is made of wood chips.

[0016] Preferably, the density of the particleboard is 600~1500 kg / m³.

[0017] Compared with the prior art, this application has the following advantages:

[0018] 1. From a cost perspective, the novel composite structure of this application integrates the structure of multi-layer wood veneer and particleboard, significantly reducing production costs. Firstly, it significantly reduces reliance on high-quality large-diameter timber. Traditional multi-layer plywood has stringent requirements for raw materials; high-quality large-diameter timber is scarce and expensive. However, the novel composite structure of this application, through the reasonable combination of particleboard, can utilize a large amount of small-diameter timber and branches as raw materials. These materials are widely available and inexpensive, effectively reducing raw material costs. Secondly, the production process is simplified. Multi-layer plywood requires multiple hot-pressing processes to laminate the veneer, increasing costs and increasing the risk of various quality problems. The novel composite structure of this application, due to the high surface flatness of the particleboard, allows for direct veneer processing, reducing the complex steps involved in multi-layer plywood veneer processing, lowering manpower and material consumption during production, and further saving costs.

[0019] 2. In terms of performance, the novel composite structure of this application combines the advantages of multi-layer plywood and particleboard, achieving a comprehensive improvement in performance. Regarding strength and nail-holding power, the rational configuration of the multi-layer wood veneer significantly enhances the board's strength. Particleboard originally has relatively weak strength and nail-holding power; however, with the addition of multi-layer wood veneer, especially in areas requiring significant external force and fixed connections, the nail-holding power is significantly enhanced, better meeting the strength requirements of furniture manufacturing, building structures, and other fields. Simultaneously, the multi-layer wood veneer, distributed in different locations within the particleboard, enhances the overall toughness of the board, improving its impact resistance. In terms of waterproofing, the multi-layer wood veneer, to a certain extent, acts as a barrier against moisture, improving the poor waterproofing performance of particleboard. When the board is in a humid environment, the multi-layer wood veneer can delay the penetration of moisture into the particleboard, reducing the possibility of expansion and deformation due to water absorption, thus extending the board's service life.

[0020] 3. Furthermore, the composite structure of this application offers diverse board structures with excellent adaptability. The particleboard-on-top structure provides the board surface with the high flatness characteristic of particleboard, facilitating various veneer finishes and meeting the needs of applications requiring high-quality surface decoration, such as furniture surfaces and interior decoration. The wood veneer-on-top structure emphasizes the board's high strength and nail-holding power, making it suitable for applications requiring high strength and stability, such as flooring and load-bearing structural components. The addition of reinforcing layers such as fiber mesh and bamboo blinds further enriches the board's performance, allowing for flexible adjustments to the reinforcing layer materials to meet the specific needs of different applications, such as enhancing fire resistance, sound insulation, and thermal insulation, thus satisfying diverse market demands.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.

[0029] Secondly, it should be noted that in the description of this application, the terms "upper", "lower", "left", "right", "front", "back", "inner", "outer", etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0030] This application provides a novel composite structure board, comprising at least one layer of wood veneer 1 and at least one layer of particleboard 2, wherein the at least one layer of wood veneer 1 and at least one layer of particleboard 2 are randomly arranged and bonded together.

[0031] In terms of structural assembly, a flexible assembly structure is adopted, consisting of N layers of wood veneer 1 and N layers of particleboard 2. The size of each layer of wood shavings and the thickness of each layer of wood veneer are adjustable. Specifically, N can be any integer between 0 and 10000.

[0032] For example, the composite structure of this application comprises wood veneer 1, particleboard 2, wood veneer 1, particleboard 2, wood veneer 1, particleboard 2, wood veneer 1, particleboard 2, and wood veneer 1 connected in sequence, and each veneer is bonded and fixed together. Alternatively, the composite structure comprises particleboard 2, wood veneer 1, particleboard 2, wood veneer 1, particleboard 2, wood veneer 1, particleboard 2, wood veneer 1, particleboard 2, and wood veneer 2 connected in sequence, and each veneer is bonded and fixed together. Still alternatively, the composite structure comprises particleboard 2, wood veneer 1, wood veneer 1, wood veneer 1, wood veneer 1, wood veneer 1, wood veneer 1, particleboard 2, and wood veneer 1 connected in sequence, and each veneer is bonded and fixed together.

[0033] Furthermore, the composite structure of the board material of this application may also include at least one reinforcing layer, which is disposed between the wood veneer 1 and the particleboard 2, wherein the reinforcing layer is selected from at least one of fiber mesh, bamboo curtain, thin steel plate, aluminum foil, metal mesh, and cement fiberboard.

[0034] Specifically, if fiber mesh is selected as the reinforcing layer material, glass fiber mesh, polyester fiber mesh, aramid fiber mesh, etc., are all acceptable. Glass fiber mesh has high strength and high temperature resistance; polyester fiber mesh has good flexibility and strong corrosion resistance; aramid fiber mesh has ultra-high strength and wear resistance. The mesh count of the fiber mesh can be selected between 40 and 100 meshes depending on actual needs. If bamboo curtain is used, high-quality bamboo should be selected and processed into bamboo curtains through splitting, weaving, and other processes. The thickness of the bamboo curtain is generally 2 to 5 millimeters. In addition, other reinforcing materials, such as thin steel plates and aluminum foil, can also be considered, depending on the performance requirements of different application scenarios, which will not be elaborated here.

[0035] The novel composite structure of the sheet material of this application involves a series of meticulous controls in the production process, including material selection, thickness design, and assembly method, in order to achieve a balance between excellent performance and cost-effectiveness.

[0036] For example, the material of wood veneer 1 can be selected from various types of wood such as eucalyptus, pine, mixed hardwoods, poplar, fir, birch, alder, and rubberwood. For example, the wood veneer can be: rotary-cut veneer from logs (thickness 1.0-3.6mm) or solid wood core veneer (thickness 5.0-15mm). Eucalyptus is hard, has good toughness, a relatively short growth cycle, is widely available, and has relatively controllable costs; pine has good elasticity and breathability, and a beautiful grain; although there are many types of mixed hardwoods, various wood resources can be fully utilized to reduce costs; poplar is relatively light, affordable, and has good processing performance; fir is light and soft, has moderate strength, and has certain natural anti-corrosion properties. When selecting materials, wood with uniform grain and no obvious defects such as decay or insect infestation should be chosen. Logs are turned into veneers of appropriate thickness through rotary cutting or slicing processes. The veneer thickness can usually be flexibly adjusted within the range of 1-3 mm, and the specific thickness is determined according to actual production needs and the overall design of the board.

[0037] For example, the material of particleboard 2 is wood chips. Particleboard 2 has a wide range of raw material sources, including small-diameter timber and branches left over from the aforementioned wood processing. These chips are shaving and sifted, and then an appropriate amount of adhesive, such as urea-formaldehyde resin or phenolic resin, is added. The selection and amount of adhesive must be strictly controlled to ensure both the bonding strength of the particleboard and compliance with environmental standards. The density of particleboard 2 is generally set between 600 and 1500 kg / m³ to balance strength and cost.

[0038] Thickness Design: For boards with the particleboard surface on the top layer, taking an overall thickness of 18 mm as an example. The thickness of the top layer of particleboard 2 can be set to 6 mm. The total thickness of the N layers of wood veneer 1 immediately below it is set to 3 mm (1 mm per layer, 3 layers in total). If a fiber mesh is used as a reinforcing layer in the middle, its thickness can be ignored. The next N layers of wood veneer 1 have a total thickness of 6 mm (1 mm per layer, 6 layers in total). The second layer of particleboard 2 has a thickness of 2 mm, and the bottom N layers of wood veneer 1 have a total thickness of 1 mm (1 mm per layer, 1 layer in total). This thickness layout ensures both the flatness and decorative appearance of the particleboard surface, while ensuring overall strength through multiple layers of wood veneer and reinforcing layers. For boards with veneer on the top layer, the overall thickness is also calculated at 18 mm. The total thickness of the top layer of wood veneer 1 can be set to 6 mm (1 mm per layer, 6 layers in total). The thickness of the particleboard 2 below it is 6 mm. If bamboo mat is used as a reinforcing layer in the middle, its thickness is set to 3 mm. The next layer of particleboard 2 is 2 mm thick, and the total thickness of the bottom N layers of wood veneer 1 is set to 1 mm (1 mm per layer, 1 layer in total). In actual production, the thickness of each layer can be flexibly adjusted according to different application scenarios and customer needs, such as furniture manufacturing and architectural decoration. For example, when used as a flooring substrate, the thickness of the bottom layer of wood veneer 1 can be appropriately increased to improve wear resistance; when used for interior partitions, the ratio of particleboard 2 to wood veneer 1 can be adjusted to reduce costs while ensuring strength.

[0039] Assembly Method: In the assembly stage, firstly, the prepared bottom N layers of wood veneer 1 are laid flat on the worktable, perpendicular to the wood grain direction. Then, a layer of particleboard 2 is evenly laid on top, ensuring uniform particle distribution and avoiding localized differences in density. Next, N layers of wood veneer 1 are laid, maintaining the perpendicular wood grain direction and ensuring each layer is tightly adhered. Afterward, a reinforcing layer (fiber mesh, bamboo mat, thin steel plate, etc.) is laid, smoothly covering the wood veneer 1 and ensuring full contact. Then, a second layer of particleboard 2 is laid on the reinforcing layer, and finally, the top N layers of wood veneer 1 or particleboard 2 (depending on the specific structure) are laid. After assembly, the boards are sent to a hot press for hot pressing. The hot pressing temperature is generally controlled between 150~180℃, the pressure is adjusted according to the board thickness and material characteristics, usually between 1~3MPa, and the hot pressing time is determined based on the board thickness, generally 1~2 minutes per millimeter of thickness. During the hot-pressing process, the adhesive cures under heat and pressure, firmly bonding the various layers of material together to form a complete new type of board. During production, the material selection, thickness design, and assembly method can be further adjusted according to the specific performance requirements of different application scenarios, such as moisture resistance, fire resistance, and sound insulation. For example, in humid environments, adhesives with good water resistance and reinforcing materials with strong moisture resistance can be selected; in locations requiring fire resistance, fire retardants can be added or materials with good fire resistance can be used as reinforcing layers.

[0041] like Figure 1 As shown, the novel composite structure board provided in this application includes a wood veneer 1, a particleboard 2, a wood veneer 1, a particleboard 2, a wood veneer 1, a particleboard 2, a wood veneer 1, a particleboard 2, and a wood veneer 1 connected in sequence. First, glued wood veneer 1 is laid (the top and bottom surface layers of wood veneer 1 are not glued), then a layer of particleboard 2 is laid, then another layer of glued wood veneer 1 is added, then another layer of particleboard 2 is added, and so on. Then, it is hot-pressed in one step to form a composite structure board core with a rotary-cut wood veneer surface. It can be sanded and then finished, or it can be sold directly as a sofa board or packaging board without sanding.

[0046] Example 4

[0047] The novel composite structure plate provided in this application can be referenced from Embodiment 1, except that a fiber mesh is added as a reinforcing layer in the middle of the plate to further improve its strength.
